Creating a Library Device

Creating a new component part in a library has three steps. You must follow these steps as they build upon each other.

To start, open a library. Use the File menu Open or New command (not the USE command).

Create a Package

Packages are the part of the device that are added to a board.

Click the Edit Package icon and edit a new package by typing its name in the New field of the dialog box.

Set the proper distance GRID.

NAME and place PADs properly.

Add texts >NAME and >VALUE with the TEXT command (show actual name and value in the board) and draw package outlines (WIRE command) in the proper layers.

Create a Symbol

Symbols are the part of the device that are added to a schematic.

Click the Edit Symbol icon and edit a new symbol by typing its name in the New field of the dialog box.

Place and name pins with the commands PIN and NAME and provide pin parameters (CHANGE).

Add texts >NAME and >VALUE with the TEXT command (show actual name and value in the schematic) and draw symbol outlines (WIRE command) in the proper layers.

Create the Device

Devices are the "master" part of a component and use both a package and one or more symbols.

Click the Edit Device icon and edit a new device by typing its name in the New field of the dialog box.

Assign the package with the PACKAGE command.

Add the gate(s) with ADD, you can have as many gates as needed.

Use CONNECT to specify which of the packages pads are connected to the pins of each gate.

Save the library and you can USE it from the schematic or board editor.
